GOMTBINED FEED-VTATEL'R. HEATER A3153) To all whom it may co'lwer'n:

Be it known that I, "nannies J. Jonnson, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements in CombinedFeedVVater Heaters-and Grease and Oil Separators, of which the followingis a spec fication.

This invention relates to apparatus for separating oil, grease, etc.,from the waters of condensation received from the condenser operatin inconjunction with a steam engine, an to also act as a feed water heaterfor the boiler, and it is the object of the invention to provide anapparatus of this character which is compact and cheap in constructi i.

In carryihg out the invention I provide a series of nested tanks,communications bealso provided for drawing oh" the oil, grease,

etc., from the top of the Water. A heating coil extends around and isconnected to the outer tank for the purpose of heating the Water beforeit is fed to the boiler. It is sometimes desirable to draw oi? the waterfrom the tanks for the purpose of making repairs or cleaning theapparatus and means for this purpose are provlded in the bottom For thepurpose of relieving the tanks of any undue pressure, which may becaused by steam conveyed by the waters of condensation or otherwise, Iprovide a vapor outlet at the top of the innermost tank. I

In the drawings accompanying and forming a part of this specificationFigure 1 is a sectional side elevation of my improved apparatus. Fig. 2is a plan fiew with the covers removed, and Fig. 3 is a plan view 7oiione of the'sections of the cover for the two'outer tanks. v

The invention consists of a series of nested tanks 1, 2, 3 and 1} havingabuse 5 vided with standards 6, The tops ofthe tanks 1 and 2 areprovided with a cover or head 7 and the tanks 3 and i with head or coverin the form of segmental plates 8.

The sides of e tanks are secured to the 5 and th eads 7 and S in ansuitabie manner, as hoits 9. v

Communication from the innermost tr iii means of a plurality of pipes 10which e);- tend up from near the bottom of the inner tank ii andconnected to the tank 2 near the top. thereof, as at 11. the tank 2 tothe next adjacent tank 3 is lay means of pipes 12, similar to pipes 16,e? tending up from the bottom of tank and connected. to tank 3 near thetop thereof, at 13. Communication from the tank 3 to the next adjacentor outside tank i is by means of pipes 14:, similar to pipes 10 end of12, extending up from near the bottom tank 8 and, connected to the tank4; near t top thereof, as at 15. It will be notedth..t the pipes 10 donot extend down into the tank 2; nor do the pipes 12 extend dovan intothe tank 2 as fares the pipes Li tend into tank 3. However, the. connedtions of the pipes 19 with the tank 2 higher'than the connections of thepipes 12 With tank 3, and the connections of the 12 with. the tank 3 arehigher than the {10% nections of the pipes 14; with tank 4, so as flowoutlet 17;

The apparatus is connected to the can denser of a steam engine, or othersource of supply of Water from which it is desired separate oil, greaseand the like by 18 extending up through the bottom 0 innermost tank 1 toa point near of the tank, as at 19. Pipes 20, 21, and extend up throughthe bottom of each tank 1, 2 and 3, respectively, to a point just belowthe normal level of the water in each of said tanks, and are provided attheir lower ends with valves or pet cocks 23 to draw off any grease, oiior the like which accumulates on described hereinafter.

Theoperation of the apparatus is substantially as follows: The tanks 1,2, 3 and e are first filled with pure cold water (indicated in a generalWay by A) passing through 1 to the next adjacent outer tank2 is byCommunication froti' tank 1 as far as the pipes 12 extend into tofacilitate the [iowing of the water from of a outer tank 4i is aisoprovided with an "vsthe top of the Water, and to be more fully pipe 24:connected to any suitable source of ovri n ..-1n n or the bottom iiiilriino the top of tank ii 1i from near no bottom of tank 2 into or tankand. through the pipes 14- the b i of tank 3 into the top ,eni; whentins: tanks z filled it Wiii inciicnieri by 011 overflow 3013 theoutlet- The waters of condense on or steam "ining' oi gense and otheriorei {I} smnro from the condenser of the stern; en gine for instance,is introc lueed iniio the oppnrums by pipe 18 passing up through thebottom of rank 1 to a point near the top the of, time raters ofcondensation being id the pipe passing up through wore]? in tank 1,materially cools we're 01f eoiuionsation.
